While fries are baking, heat deep saucepan over medium-high heat and add ground turkey. Use a potato masher to break down the turkey a bit then add diced onions, grated garlic, salt, pepper, and carrots.
Stir turkey and vegetable mixture frequently with a wooden spoon until turkey is cooked through and veggies are soft about 10-12 minutes.
When turkey starts to become golden brown and delicious, add flour and cook for 30 seconds stirring frequently.
Add chicken broth to the pan and use a wooden spoon to scrape up browned bits from the bottom. Stir in frozen vegetables then bring mixture to a boil. Reduce heat to low and simmer 5-10 minutes. Stir every minute or check the thickness of the gravy. Feel free to add more broth if the sauce is too thick.
When the sweet potato fries are hot and ready, add fresh dill to the turkey mixture. Check for seasoning and add salt or pepper if necessary.
Serve sweet potatoes on top of the turkey mixture to create Shepherd's Pie or simply serve side by side.
Serving size may vary based on size of sweet potato fries. In general, aim to divide total mixture by four to determine serving for one.
